Because "degree of parallelism" is standard terminology, I guess.
Also, consider that we have the related but actually sorta different
GUC max_worker_processes. I think max_parallel_workers to control the
per-query behavior and max_worker_processes to control the global
system behavior would be confusing - those names are very close
together.
